Best route to go for new dac?

Op, there are so many choices and everyone has their favorite. I suggest you avoid the "measurement" trap, the lowest SINAD numbers will not equate to the best sound. Audition a few that have a well put together analog stage and choose what you like to hear.
In a resolving system, the DAC is much more than a chip. 
Ignoring the sales pitch at the beginning, this video is worth watching to understand the importance of the analog stage.

Edit...."The Best SINAD #s"....Did not mean to say "Lowest".  Higher is actually preferred.
